All my brands of stainless mags are magnetic. You're speaking on broad terms.

"Broad terms?"  I'd say your statement was,  if any.

"Carbon steel and stainless steel are both magnetic." Not entirely.  

In specific terms this sums it up, basically 2 categories for simplicity;


Magnetic:

(Ferritic and Martensitic): Many steel magazines (such as 400-series stainless or carbon steels) are highly magnetic and will stick firmly to magnets.

Non-Magnetic

(Austenitic): Some magazines (especially those crafted from high-nickel and high-chromium 300-series stainless) are entirely non-magnetic.

And then the outliers:

Some stainless steel magazines sit in a gray area, possessing just enough magnetism for a basic fridge magnet to stick. Those that take on slight magnetic properties from heat treating and /or cold working fall into this category.

Got 4 from GT Distributors and they shipped super fast. Arrived loose in a padded envelope and they said they would be shipped minus their plastic packaging to save of shipping cost. The mags work in my Grit Grips 48 frame with their magwell. Now to get a local match to test them out live fire.

Perhaps I misunderstood your original comment. Were you saying that the mags are carbon steel because they are magnetic?

No sir, just stating the only fact that I am sure of regarding these new mags.

I've read plenty of speculation as to material composition and finish/treatment but zero actual facts.

I'm going to guess heat treated carbon steel, because that's what Mec-Gar says the tubes for their Glock mags are made of.

Just got one from Aim.
Ordered Wednesday night via snail mail shipping. So 3 day shipping.

Heading to the range in a bit but...
The 15rd I received doesn't drop free when empty.

ETA.

The 15 rounder worked great. Locks the slide back etc. The extra weight and little bit of length isn't noticeable at all.
Getting that 15th round in is a mofo.
It does NOT drop free in my G48 empty or loaded, factory 10 rounders drop free either way.

Just ordered 3.  Don't even have my 43X anymore.  Trying to find an upper to pair with a GritGrips frame.
Going to order a thinner aluminum baseplate from Excess Arms (for the PSA Micro Dagger magazine) to try on one of these.

One of the guys at GlockTalk posted about modifying both a PSA base plate and an Excess Arms base plate to fit the Glock mags. Start here and see the posts from FrankenGunBuilder.

Today I didn't run 400 rounds through my 43X with my new three (3) 15rd OEM magazines, but around 150rds trouble free rounds. Plus I used an Uplula magazine loader to save my fingers since springs are stiff. No issues, period. Now using them for my daily summer carry magazines. Thanks Glock!

Put a couple hundred rounds through the two 15 rnd mags I have, locked back last rnd, drop free and zero issues. Will be getting more soon.

I got out to the range today too. Ran about 100 rounds through one of my new mags and it did great. No malfunctions, Contrary to my last post it drooped fine and always locked back. Great magazines if the base plate doesn't bother you. I'm fine with it so when the rush slows down I will get more. Now to Zero that Vortex Defender ccw. I actually spent those rounds doing just that but I'm not satisfied.

Mrgunsandgear was reporting that in his older G43 silver slide model the new mags would not drop free, but the newer black slide models it did.

I wonder if this is what's happening. It appears they may have changed the magwell mid production somewhere.

Back when I got my 43x MOS with the Shild Arms optic. I read somewhere they made a very small change to the frame. It helped the S15 mags work better. I'm sure that wasn't the reason but the very small change was for the better. I cought hell for that post. Now it's more likely to be true... I hope the haters are seeing this.

Received my mags from GT over the weekend. I have an older 43X and the mags ran flawlessly, locked back and dropped free with about 300 rounds.

Pretty happy with them and impressed with the GT service. Quick shipping and had them within a few days

Grit Grips 43x/48 frame is nice. Feels better than stock as they gave it a smidge more length and width in the grip. Stippling is better and grab their magwell also. Just enough to help with forcing your hand up into the grip better, if you have medium to large hands. I went tan for a 2 tone look.

I really want to standardize with the new Glock mags. I'm going to ditch the Shield ones probably.

However I picked up a CZ75 conversion kit prior to the OEM magazine announcement. I might run it to see how it functions.

These use the same mags. 13 rd flush fit Jericho compact. Cz 75 compact and cz75 full size

I think Mecgar could make a 13 round true flush fit.

1/3 of the way there.  Got my 3 43x mags and a grit grips frame.  

working on getting the rest.  probably will just end up buying a new 43x to cannibalize and sell off the oem frame

Trigger wasn't as bad as I recall the smaller glocks being.

Regardless, 5 lbs striker spring, some polishing and a polydat helped.

I would have rather they'd just went with 13-14 rounds instead of having that bulky base plate that looks like an afterthought and is essentially an extended magazine.

Im hoping its not as apparent in person.

I have a new 43X COA and was able to get a pair of the 15 round mags.

Tried various ammo, ball is the only thing that is reliable.

Anything else is FTF or stovepipe.

I’d take that version as I would prefer to keep it as compact as I can.  I like the grip length of the gun, I don’t really want to extend it.

Saw this on r/glocks...Damn, I just got 3 last week. They've been fine with 115g ball, but I haven't tried my 147 Rangers yet.

Here I thought maybe we'd finally have a reliable 15rd mag. I tried the Shields, no go. Tried the Derya's, work fine with FMJ but not HP's....

And same, zero issues with my mags and 115 ball and 124 HST thus far in my gun.

I have two magazines.  Both work just fine with ball and my carry hollow points. Lock the slide back when empty, no problems whatsoever. I always test new magazines with ball and duty ammo before I use them in everyday carry.
The little bit longer baseplate does not bother me at all. I am very glad I got them, and will be getting more. Any problems with the magazines out in the wild, while unfortunate I’m sure Glock will make right.

I too wish Glock had gone with a true flush fit low profile mag of 13-14rd vs the extended 15rd.

GritGrips magwell kind of covers the large Glock 15 rd magazine baseplate.

Bought a new 43X two weeks ago that came with the 15 rd mags. Ordered two more online and got those in.

Took them all to the range today and fired about 200 rounds total through them. One magazine failed to lock back the slide when empty two times. The other three magazines worked 100%.
